The Little auk is, as the name indicates, the smallest of the auks. It weighs only around 160 grams and only measures around 20 centimeters. Even the small Atlantic puffin, around 33 cm long, seems big in comparison. The auk's wings measure only 34 to 38 cm, which means that in order to fly it must beat the wings very fast. It usually also flies very low over the sea surface. When diving, the wings can be used as paddles, just like among the penguins.
